Benefits of technology

[0007]The main objective of the invention is to provide a method for improving data writing speed of a diskless computer.
[0008]The method in accordance with the present invention is applied to a diskless computer connecting to a remote server that has at least one disk drive and having a central processing unit (CPU), a host bus adapter (HBA) and a storage unit. The method comprises acts of retrieving writing data commands by the CPU from an operating system kernel executed by the CPU, writing the requested data to a storage unit in the diskless computer by the CPU, returning a response of finishing writing data to the operating system kernel by the CPU and writing data stored in the storage unit to the at least one disk drive of the remote server by the CPU. Therefore, the operating system kernel receives the response of finishing writing data even though the loading of the network is heavy. Consequently, the speed of the diskless computer writing data increases.
[0009]The other objective of the present invention is to read data from the storage unit when the diskless computer tries to read data from the remote server if the requested data are stored in the storage unit. Therefore, the speed of the diskless computer reading data increases even though the loading of the network is heavy.

Problems solved by technology

Therefore, the speed of the diskless computer reading data increases even though the loading of the network is heavy.

Embodiment Construction

[0014]With reference to FIG. 1, a method for improving data writing speed of a diskless computer in accordance with the present invention is applied to a diskless computer (10).

[0015]The diskless computer (10) connects to a remote server (30) having at least one disk drive (31) over a network (20), such as the Internet. Each disk drive (31) may be but not limited to an integrated device electronics (IDE) disk drive, a small computer system interface (SCSI) disk drive, a serial advanced technology attachment (SATA) disk drive, a removable disk array, a storage area network (SAN) storage device or the like. The diskless computer (10) at least comprises a central processing unit (CPU) (11), a host bus adapter (HBA) (12) and a storage unit (13).

[0016]The CPU (11) is for executing an operating system kernel.

[0017]The HBA (12) is connected to the CPU (11) to allow the diskless computer (10) to connect to the remote server (30). Therefore, the diskless computer (10) accesses the at least o...

Abstract

A method for improving data writing speed of a diskless computer is applied to a diskless computer connecting to a remote server that has a disk drive and having a central processing unit (CPU), a host bus adapter (HBA) and a storage unit. The method has acts of retrieving writing data commands by the CPU from an operating system kernel executed by the CPU, writing the requested data to a storage unit in the diskless computer by the CPU, returning a response of finishing writing data to the operating system kernel by the CPU and writing data stored in the storage unit to the disk drive of the remote server by the CPU. Therefore, the operating system kernel receives the response of finishing writing data even though the loading of the network is heavy. Consequently, the speed of the diskless computer writing data increases.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a method, and more particularly to a method for improving data writing speed of a diskless computer.[0003]2. Description of Related Art[0004]Many enterprises require multiple computers for staff to work and may use multiple individual personal computers (PCs) or a WAN boot personal computer (WBPC) service to build their computer systems. As described below, individual PCs suffer from data security and management problems and have a high per unit cost, so WBPC systems may be preferred. The WBPC service comprises a WAN boot server (WB server) and at least one WBPC. The at least one WBPC is a personal computer without any disk drives, and the operating system, application programs and user data of the WBPC are stored in disk drives in the WB server. The WBPC must have a host bus adapter (HBA) installed to connect to the WB server and access the disk drives in the WB server over the Internet...
